Arsenal are sweating on the fitness of Cesc Fabregas ahead of Wednesday's Champions League quarter-final clash with holders Barcelona. The Spanish schemer limped off last weekend's 1-1 draw at Birmingham after a fierce tackle from Craig Gardner. While admitting that Fabregas is not 100% fit, manager Arsene Wenger still hopes his team captain can recover in time for the kickoff. "We will assess the situation, if he has full capacity we will play him," the Gunners boss said. "The medical staff tell me he could be available and that will be decided in the warm-up, that's how late we will leave it. "We have a squad of 19 players so I have considered the possibility of leaving him out completely. We will give him 24 hours more, but I don't know if he will be available. "If he is not capable to play I would not even play him on the bench." Fabregas missed Arsenal's last Champions League game; a 5-0 drubbing of Porto in the round of 16 return leg.
